It is witnessed throughout all scripture: Moses and the burning bush (Exodus 3), the fire that fell from heaven on Mt Carmel (1 Kings 18), the chariots of fire that Elisha's servant's eyes were opened to see (2 Kings 6), the divided fire of tongues that set on the heads of those men and women in the upper room on the day of Pentecost (Acts 2), the "flame of fire" we are told God makes his ministers into (Hebrews 1:7), the baptism of fire that only Jesus is capable of sending spoken of in Matthew 3:11.

They are all fire...but much different from worldly fire. They are all visible to some degree, however, visibly different from earthly fire. The difference between earthly fire, man-made fire, and the divine fire I speak of is a difference that is literally worlds apart. One is earthly and produces death. The other is heavenly and produces life. One is man-made and eventually burns out. The pother is the very breath of God and it never dies, it never loses power, it never flickers out, it burns forever.
